SPARK ARRESTER Application tiled April 26,

This invention relates to spark arresters for use upon and in conjunction with chimneys contemplating a housing member positioned upon the top of the chimney and having a shelf positioned at an appropriate height thereof and having its respective side Walls spaced therefrom to permit smoke to pass outwardly from the chimney but deflect sparks downwardly within the chimney in order that the roofs of houses may not be set afire.

Another object resides in the provision of a cover arranged upon the upper portion of the housing member and having a relatively small cut-out portion provided therein immediately above the shelf to permit the exhaust of smoke from the housing member.

With the above. and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illus- `trated in the vaccompanying draving and box like housing member 12 pointed out in the appended claim..

In the drawing t Figure 1 is a fragmentary elevation of a chimney with the present invention applied and used in conjunction therewith;

Figure 2 is a vertical sectional view of the invention; and

Figure 3 is a transverse section illustrating the arrangement and support of the shelf with the housin member.

Referring to t e drawing in detail, wherein like characters of reference de'note corresponding parts, the reference character' 10 indicates a chimney having a shelf or enlarged portion 11 formed upon the upper end thereof; all of which is of the usual and conventional form and in no-way consists of any subject matter pertaining to the invention:

The invention residesin the provision of a referably formed of thicknesses of coarse an fine wire or other reticulated or foraminated material and which supports Within its enclosure, defined at an ap ropriate point in the height and transversel) thereof, a correspondingl `constructed'she f 13 falling short of the d1- mensions of the box like housing 12 and having hooks 14 secured within the corners 1926. Serial No. 104,794.

thereofwhich extend inwardly from the corner portions of the housing in the manner as illustrated in Figures 2 and 3 of the drawing. l

A cover 15 being preferably constructed of coarse wire meshing, having its respective edges bent downwardly upon themselves and fitting over the opposite and outer sides of the box like housing 12 and including an elongated cut-out portion 16 therein is positioned immediately upon and in spaced relation to the shelf 13. Retractile springs 17 having hooks 18 provided upon their upper ends and fitted within the opposite and downwardly extending side edges of the cover 15, While their opposite ends are associated with angularly disposed substantially L-shaped attaching plates 19 lying flush with the outer surface of the shelf or enlarged portion 11 and the chimney 10, While the opposite portions thereof engage the under sides of such enlarged portion, whereby the device in its en tirety may be positioned against accidental displacement and retrograde movement upon the chimney, directly above the flue thereof in order that sparks emitted from the chimney will be deflected downwardl within the chimney flue, but yet permit t e Smoke t0 ass therethrough and around the side edg' ing thereof and through the side walls of the housing. The cover 15 serves as an auxiliary to the shelf 13 to catch and deflect such sparks as may pass between the side edges of the shelf and the inner side Walls of the housing member 12 and upon the outer side ofthe shelf 13.

The above entitled invention offering a device which may proveof great value to persons having faultyr chimneys emitting volumes of sparks and which will materially reduce chimney fires.

The invention is suceptible of various changes in its form,'proportions` and minor details of construction, and the right is herein reserved toV make such changes as proper- 1y fall within the scope of the appended claim.

Havingthus described my invention what I claim is:

A spark arrester comprising a housing member arranged above the discharge end of a chimney, a combined shelf and. baille plate horizontally disposed within the housin member in spaced relation to the ends and side walls thereof and supported at its cor-
